Under pressure!

Over the last 2 years I have gone from a size 18 (cant believe I was that big!) back to my pre pregnancy size 12. My husband and I have just been away without the children to a wedding in Italy and whilst there I received some attention from other men which my hubby wasn't happy with. I did nothing to encourage anything and didn't particularly notice tbh.

Cutting a long story short, blazing row as a result, but things went strange when my hubby (when very drunk) said that it actually was a major turn on for him!

I nervously reminded him of it the next morning and after initially denying it he opened up and said that he would love me to sleep with another man. I was a little shocked to say the least!

Since then he talks about it a lot and has even suggested one or two people we know. I want to make him happy and have confided in a girlfriend who says go for it as it's quite common for men to like it! Is she right? I am 50/50 as worried it could backfire on both of us.
